The US newlyweds were on their honeymoon. Gabe Watson, an experienced rescue diver, was exploring a submerged wreck with his wife when she died. It was her first big diving trip, after she had been persuaded by her husband to explore the deep, turquoise waters of the Great Barrier Reef.

One witness said the couple appeared to be locked in an unnatural embrace at a depth of about 50ft before they separated, with Watson heading to the surface while his wife sank to the ocean floor. A leader of the dive spotted the stricken woman and brought her to the surface, but she could not be revived.

Travel health and the emerging specialty of "wilderness medicine" have obvious overlap. Dr. Paul Auerbach is one of the leaders in wilderness medicine: helping found the Wilderness Medical Society, co-author of A Field Guide to Wilderness Medicine and numerous journal articles and serving as faculty to the Stanford Fellowship in Wilderness Medicine.

His blog, Medicine for the Outdoors, is celebrating the two year anniversary. For those who haven't yet had a chance to visit, it is filled with practical information and advice for those exploring their environment and wanting to come back from the experience in good health. Travel and expedition medicine is the focus of my career and I find myself citing Dr. Auerbach's work and information, in my work. He is one of the pioneering physicians who helped elevate this field of medicine to a new and unique specialty.

A visit to his blog will allow the reader to learn about things from jellyfish stings and dislocated shoulders on the trail to malaria medications and outdoor recreation. This is truly an opportunity to read, first hand, the information from a leader in wilderness and expedition medicine. I highly recommend a visit to his blog, if you get a chance. Oh, and don't forget to congratulate him on his two-years of dispensing great advice!

I think I just figured out where I want to be buried when I die. Check out this underwater cemetery, which opened last fall about about 3 miles off the coast of Key Biscayne.

The Neptune Memorial Reef was built as the "perfect final resting spot for those who loved the sea", AP reports. Its creators hope that one day the reef will cover 16 acres and have room for 125,000 remains. The artificial reef's first phase allows for about 850 remains.

In March, the remains of 93-year-old diver Bert Kilbride - who called himself "The Last Pirate of the Caribbean" - were placed atop a column of the reef's main gate, because of his contributions to the sea. Kilbride was named the oldest living scuba diver in this year's Guinness Book of World Records.

I have to tell my Mom about this guy. She might appreciate that he made it to the age of 93, being a diver and all. A fortune-teller once told her that "danger awaits me in the water." Ever since then, she expects I'll get eaten by a shark every time I dive. How cool would it be to get eaten by a shark after you are already dead a buried? I can't wait to tell my Mom about it. Tomorrow. I don't think she would appreciate the sentiment on Mother's Day.

Happy Mother's Day!

The Great White Shark attack off the coast of San Diego yesterday (and Mark Shaw's insightful comments about it) got me thinking about wetsuits. Doesn't it seem that most shark attacks happen because sharks confuse swimmers or surfers with seals? (See photo to get an idea of what such lovely encounters might look like.)

Here is my question. Why are most wetsuits black then? The majority of the all wetsuits I have ever rented and worn for diving have been black; hence they make you look like a seal. They might have a few color accents, but I am not sure the vision of sharks is good enough to fully appreciate them.

The guy who died in 2004 after a shark attack in Northern California was wearing an olive camouflage wetsuit that made him blend into the rocks (and possibly look more like a dolphin than a seal. Sharks like dolphins, too.) This page has a lot of interesting information about that attack.

Some sources, the surfing handbook being one of them, say the wetsuits with big color contrasts make you look like a fish, which is apparently not helpful, either. I have to say, I have never seen a 6-foot fish of crazy colors though.

Is it difficult to dye neoprene, say, all white or all orange? Would that help or is that wishful thinking?

Belize has been on my "places to dive" list for years. At the same time, I get anxious every time I think about diving in Belize. Years ago, I knew somebody who died while diving the Blue Hole, the infamous collapsed limestone cave more than 400 feet deep. She was an experiences diver, but panicked. Ever since then, the Blue Hole has sounded a little scary to me.

After reading this USA Today article, it sounds like I should get over myself and finally go there soon because Belize's coral reef is vanishing quickly. A potent mix of coastal development, tourism, overfishing, pollution and climate change has apparently damaged an estimated 40% of the Belize reef system, a UNESCO World Heritage Site and the Western Hemisphere's largest barrier reef, that attracts more than a third of Belize's 850,000 annual visitors. Ouch.

As the weather begins to get a little less wintery we are already beginning to discuss our summer trips. A beach trip is always a favorite. Laying on the shore with a bit of swimming and relaxation are just what's needed after a long, cold winter. But there are a few hazards that can ruin a good trip to a dive spot or beach -- best to start thinking about them now, so if there is a problem, you'll be ready to deal with it.

One of my most favorite quotes on the subject of bites and stings actually comes from WC Fields. "Always carry a flagon of whiskey in case of snakebite and furthermore always carry a small snake."

Jelly Fish are beautiful creatures to watch swim and some of the most interesting marine life. They can also cause a lot of pain and problems if you get stung. Jellyfish sting with their tentacles that contain thousands of nematocysts. Thus, a single creature can produce many, many stings.

The first priority, for a jellyfish sting victim, is to make sure they are still breathing properly and not having a severe allergic reaction. Burning at the site, numbness, nausea and swelling are all common reactions. A topical decontaminant is what is next. Get those stingers to stop causing problems! The nematocysts can generally be 'de-activated" with a solution of vinegar, rubbing alcohol or baking soda, poured over the wound. This will also help relieve the pain. Papain, found in meat tenderizer may also be helpful. Removal of the stingers can be aided by shaving the area, with a sharp razor and shaving cream. A local antibiotic/antiseptic cream can now be applied, with or without a low dose steroid cream. For those who just have to adventure in known jellyfish areas, a StingerSuit might be a good consideration. Oh, save the pee for the bathroom as it has not been proven to be of benefit and it is kind of gross.

There are a few famous jellies to know about. First is Chironex Fleckerii (Box Jellyfish), from Australia. This sting can be fatal to humans and extreme caution should be taken in waters where they live. The other bad-guy is Irukandji (Carukia Barnesi), also from Australia. This jelly is only about the size of a large coin and very deadly. Swimmers can often miss seeing them, until it is too close by to avoid.

Make sure to pay attention to life-guards and warning signs for the beaches you are visiting. The best advice is to avoid areas with abundance of jellyfish and head to another beach that is safer.

There's only one place in the U.S. where it's legal to swim with manatees and that's Crystal River, Florida. The friend of mine who recently moved to Florida, told me this while pulling up a Web site to Crystal River.

Yep, sure enough. The manatees arrive in droves at Kings Bay along Florida's west coast via the Gulf of Mexico starting the end of October. Picture 60 miles north of Tampa and 30 miles west of Ocala Oscala and you're there. This pristine spot is the winter home for one of the world's largest manatee herds that will frolic here until the end of March when they start heading north again.

A warning though, along with the manatees, people herd themselves here on the weekends. According to this one Web site with info on Crystal River, there are enough snorkelers in Tarpon Tampon Springs, (also called Kings Springs) that you could almost walk across the water on their backs. That sounds like an interesting sport. I wonder if you have to pay?

For this reason, the author suggests that you visit during the week, or head to one of the less visited springs. One, Homosassa Springs Wildlife Park is mentioned has an environmentally friendly twist. Here, besides just seeing the manatees, there are educational programs about them, as well as, the other wildlife in the area. Bird walks are monthly occurrences up until the end of May. If you head here June, July and August, no guided bird walk for you.

This month Lu's Birthday Party is a featured event. Lu is the park hippo and a reason for a party each January. Here's the link to the park's events page that gives the details of all the happenings through the spring. The hippo pictured is Lu.

If you do plan to swim with manatees, check out the Web site Save the Manatees Club, first. Swimming with the manatees provides a thrill, but be careful how you go about it. The activity doesn't always bode well for the manatees. Motor boats have motors, for example.

At Homossassa Springs there is an environmentally, manatee friendly excursion that sounds divine. For $40 bucks you head out in a kayak on a guided 3-hour tour. (The theme-song from Gilligan's Island just popped into my head for a moment.) The photo to the left was taken at Three Sister Springs, another option.

For more manatee info from the Save the Manatee Club, click here. Also at the site, for $35 you can adopt a manatee and get a stuffed animal as a thank-you. Put a red bow around it's neck, fasten a small box of chocolate in a heart-shaped box to it's flipper and you have a Valentine's Day present for a child. Hmmmm. Now, that's an idea.

There are several swim with the manatee tours around Crystal River, but, like I mentioned, I'd keep the manatees in mind before heading out on a motorized boat. Although, since another major spot to view the manatees is at the Crystal River National Wildlife Refuge and it is only accessible by boat, make sure you head to an establishment with reputable folks running it.

There are rules for where motorized boats can be used and where they can't be. My general feeling is that people who make their money off wildlife do a pretty good job of taking care of it. They're not likely to ruin their money tree.

To help you be in the know about appropriate manatee interactions, here's a link to guidelines from the refuge. Also, here's a Gadling post from Dolores Parker who had a personal experience swimming with the manatees last June. Even though she and her family went off-season, they did have some luck.

A friend of mine moved to Florida recently and has discovered the wonders of Florida's underwater scene. Actually, he hasn't made it to any of the places that he's salivating over whenever he browses the Web site underwaterflorida.com, but he's planning upcoming outings for whenever he has time off from work.

He showed me the section of the Web site that lists many of Florida's freshwater springs by region. If you click on each one, there's a description about what makes a particular spring unique from another. For example, Rainbow Springs is one of the clearest in Florida. Here you can snorkel, canoe and swim. There is also a hiking trail and tropical gardens. As I'm sitting in gray, cold Ohio, tropical gardens sound divine.

DeLeon Springs caught my attention, but it has nothing to do with the fountain of youth. What it does have something to do with is the Civil War. There used to be a sugar mill here that was burned down twice by Confederate soldiers. Now you can canoe and scuba dive.

Hearing my friend talk about the places he'd like to go (he's up in Ohio for the holidays) reminds me of what is so alluring about moving to a totally new state, country or even a new town. Although, there's a certain coziness about living in one place for a long enough time that it's as comfortable as an easy chair, and you've been to the same dentist or mechanic so many times that you don't even have to remember how to get there anymore, there's an edginess that's missing.

That crackle of excitement when learning to navigate the unknown and making new discoveries is hard to come by when settled down--which is why travel is as necessary as breathing. Moving to Florida, particularly this time of year, makes sense to me, particularly when there are more than 30 springs listed with directions on how to get there. Of course, moving means packing and that's another story. Still, Skybus flies to Florida and the next round of cheap seats should be posted soon.

We've written about how you can mail a postcard in a cave, stay the night in a volcano cave--or some other caves, bungy jump in a cave, paddle in a cave, and go to church in a cave. There's a whole lot more you can do in a cave and I'm sure one of us have mentioned it, but these will do for now. Missouri is the place to go for even more cave fun. It's not called The Cave State for nothing.

The reason Missouri has such cave wealth has something to do with mining. When you dig sand, limestone and lead from underground, huge caverns are the result. These left behind caverns make for terrific underground recreation facilities since the temperature stays constant year round regardless of what the weather is doing above ground.

Here's what you can do in Missouri's caves besides walking through them. You can:

• play tennis at Underground Racquets Ltd. housed in a limestone cavern in Carthage.
• scuba dive at Bonne Terre Mine in Bonne Terre that used to be where lead ore was extracted,

And in the future, hopefully, you will be able to ice-skate and kayak at Crystal City Underground, once a sand mine.

I am planning a trip to Panama. Not sure why. I don't know much about the country but I have a free Continental voucher to use up and they fly there directly from New York. That's a good enough reason for me. Plus, it sounds like a pretty interesting place.

I am sure many of you have been there already. I hear that Panama is trying to brand itself as the new, wilder (and possibly more dangerous) Costa Rica. Any recommendations? Any must sees and must avoids? Are there good diving/rafting opportunities?
